Answer:
The correct answer is:
C) if by applying rigid motions you can make them coincide
Step-by-step explanation:
Two polygons are said to be congruent or identical in form, if they have exactly the same size and shape or if their corresponding angles and sides are also equal.
When a rigid motion like - reflection, rotation and translation is applied on the polygons and they maintain the same length and shape then, they are called congruent.
So 140 is the simple interest fee of 8% so 8% that her friend is charging her is only 140. So you can add that to the original price to know ALL of what she is gonna pay but that depends of you just want the fee or the whole total which is 1890
Functions cannot have different values of y for the same value of x. Now let us check each case one at a time.
<u>First Case:</u> For the same value of x=-1, y has two different values of 7 and 1, which is not allowed in a function. Therefore, the first case is not a function.
<u>Second Case:</u> For the same value of x=-1, y has two different values of -5 and 1, which is not allowed in a function. Therefore, the second case is not a function.
<u>Third Case:</u> For the same value of x=3, y has two different values of 2 and 4, which is not allowed in a function. Therefore, third case is not a function.
<u>Fourth Case:</u> In this case no value of x is same. So, this is a function.
Answer:
(a^3-b^3)
Step-by-step explanation:
According to the formula
Combining like terms is pretty simple. First, you would identify which terms are similar to what terms. For example, you can't combine two terms that aren't similar like 2x and 3y. It would have to be 2x and 3x to combine. Next, be sure to add/multiply/subtract/divide/etc. the terms. For example, if you had the problem 2x + 4x + 3y, you would combine the "x" terms and the resultant problem would be 6x + 3y. Hope this helped :)
